y To all '1n/0m if 111mg/ concern:

Be it known that I, FRED S. Carin, al citizen of the United States, and a resident offV Newton, in the county of Middlesex and 5 State of itflassachiisetts, have invente-d an Improvement in Fasteners, ofV which the following description, vin connection` with the accompanying drawings, is a specification, like characters on the drawings representing like parts. y

This invention pertains tov improvements in fasteners, and more particularly, though not exclusively, to that type of fastener commonly used for securing carpets, rugs* or the like to floors.

In the drawings which show a Jreferred l C l y i n L. form of one einbodlment of my invention z- Figiire l is a plan view of a portion of a rug or carpet s'liowing'in dotted lines the position of an underlying fastener;

Fig. 2 is a diagrammatic viewshowiiic .the warp and weft threads to which` the fastener socket is attached and the socket prongs penetrating` these warp and weft threads and clenched thereover;

Fig. 3 is a section on the line 3-3 of Fig. l, being partly in elevation and showing the preferred form of stud and socket secured respectively to the floor and to the rug or carpet thereon;

Fig. 4 is a section on the line -t of Fig.

3, illustrating how the pile of the rug or carpet may overlie and conceal the Vsocketsecuring prongs; and

Fig. 5 is a plan view of the socket before attachment thereof to the rug or carpet.

Referring to the drawings and to the preferred form of my invention selected for illustrative purposes, I have shown a stud including a screw portion 6 and a head portion 7. The screw' portion of the stud may be entered in the floor 8 of the room or automobile in which the rug or carpet is to be used. The cooperating Socket may include a plate 9 peripherally curved upwardly and presenting a plurality of warp and stud entered therein, and a spring-holding weft penetrating prongs l0 arising therefrom. The socket casing may also include.

plate or discY llis also preferably apertured to permit passage of the head 7 of the rstud into the plane of the top of the spring-sey curing plate or disc ll which may be secured to the plate 9 by striking up and bending over the lower Aedgethereof portions 13, as best shown in Fig. 5. Where the springsecuring plate or disc 1l is curved in crosssection as shown, an annular depression l5V is provided between the spring-securing plate or disc ll and the peripheral portion of the socket. Then the prongs l() have penetrated the warp and weft threads lllof the rug or carpet, thesefprongs may be bent. inwardly and draw downwardly any warp or -weft threads lying thereunder into the annular depression l5, so that the upper surface of the carpet will show veryY little elevation kat the point underlain by the -fastener and, further, so that the prongs lO vwill be particularly effectively concealedby the pile of the rug or carpet, as best shown inl Fig. fl. Y

Where, as in the preferred form of my invention illustrated, the socket is relatively thin and wide andthe stud presents a relatively wide and thin head which when entered in the socket does not lie substantially above the plane of the upper face thereof, not only is the formation of humps or bunches in the carpet minimized, but the tendency to excessive wear of ythe carpet immediately above the fastener is to a considerable degree reduced. f

Vhile I have shown and described a preferred form of my invention, it will be understood that my invention is not limited thereto but is best defined in the following claims.

. Claims: y

l. A fastener socket for application to a carpet or the like comprising, in combination, a socket including a lower member presenting an aperture to receive the head of a stud, resilient means partially intersecting said aperture releasably to grip a member secured to said lower member, said lower member and spring-holding lmember together constituting a casing, the outer l edge of said lower member having upward- 2. A fastener socket for application to a carpet or the like comprising7 in combination, a socket including a lower member presenting' an aperture to receive the head of a stud, resilient means partially interseeting said aperture releasably to grip a stud entered therein, and a spring-holding' member secured to said lower member, said lower member and sprin'g-holding` member together constituting a easing, the outer edge of said lower member having upwardly extending` prongs adapted to be bent downwardly and inwardly to engage over the warp of the Carpet while concealed from View by the pile of the carpet, said lower member flaring` upwardly adjacent its periphery to provide a groove between its rim and said spring-holding` member into which said prongs may press the engaged warp and wett of the carpet.

In testimony whereof, I have signed my name to this specification.

FRED S. CARR.
